Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Inconsistent lighting on trees when placed/painted on

Hey Everyone.

I'm hoping someone can help me, if you check out the picture the trees on the left where placed down and positioned normally and the lighting seems to be fine. but the trees on the right have been painted on using the foliage tool. ive rebaked the lighting but its still showing like there is no shadows.

is there anything i need to check when using the foliage tool that could be causing this to happen?

Thanks in advance.

Hi Lee,

If you're using a Directional Light set to Moveable (dynamic) and a Skylight set to movable, make sure to rebuild lighting to clear any indirect lighting cache values. You should then only have direct lighting from the main light source, and the skylight will handle the fake bounce lighting.

This should be able to clear up the inconsistency you're seeing with the trees that are painted. This would at least be where I would start.

It looks like one uses lightmaps while the other uses dynamic lighting. I believe that by default objects placed with the foliage tool are lit dynamically, while regularly placed ones use lightmaps which could explain the different results you are seeing.

By default static lighting is on for all foliage items and uses their original lightmap resolution value, which can often be pretty high. Typically with foliage you wouldn't want to use lightmaps anyway for an exterior scene, at least not for foliage that should move.
